    摘要: An electrical connector adapted for staged disassembly to test for high voltage includes a plug having an enclosed electrical terminal with a first opening exposing the terminal and a socket having another enclosed electrical terminal with an opening exposing the other terminal. The socket opening is substantially complementary to the first opening to receive the plug sufficiently into the socket to electrically engage the terminals in first and second positions. A port in one of the socket or plug provides access to one of the terminals in one of the positions but is obstructed from access to a terminal in the other of the positions. The port is small enough to prevent a finger from accessing a terminal but large enough to receive an electrical meter probe for voltage testing. A latch on the box portions positions the port in each of the two positions.

    摘要: Methods and apparatus are provided for a functional high-voltage interlock system. The apparatus includes an enclosure, a high-voltage terminal, a low-voltage circuit, and a control circuit. The enclosure includes an access point that may be breached. The high-voltage terminal is disposed at least partially within the enclosure, is accessible by breaching the high-voltage access point, and is configured to be energized from a high-voltage electrical power source. The low-voltage circuit is disposed within the enclosure, and is coupled to selectively receive a low-voltage electrical signal. The control circuit is coupled to, and is configured to supply the low-voltage electrical signal to, the low-voltage circuit only when the high-voltage access point is not breached. The control circuit implements a first function and a disparate second function. The first function determines whether the access point is breached and, if so, prevents the high-voltage terminal from being energized from the high-voltage electrical source.

    摘要: A method and apparatus provide an electrical splice between different high-voltage components in a high-voltage propelled vehicle (HVPV), which enables a daisy-chain or series connection of the components. The method includes connecting a first end of a cable to a first component, a second end of the cable to a high-voltage bus bar within a second component to form a splice, and using the outer housings of the components to provide an environmental seal and electromagnetic capability (EMC) shield for the splice, rather than providing such a splice within a dedicated or shared power distribution box. A ring terminal connects to an end of a cable by a press-fitting process or a soldering process. The components can be an energy storage system (ESS), a power inverter module (PIM), an air conditioning control module (ACCM), an auxiliary power module (APM), a power steering controller, and an electrical motor/generator.

    摘要: A method includes detecting high-voltage faults, such as welded contactors or disconnected components, in a vehicle by measuring the total electrical impedance between positive and negative rails of a high-voltage bus and a ground or chassis, comparing the impedance before and after opening the contactors, and executing a maintenance response. The response includes setting an error code when the open impedance level is less than a threshold multiple of the closed impedance level. A vehicle includes a chassis, energy storage system (ESS), motor/generator, and a high-voltage bus conducting electrical current from the ESS to the motor/generator. Contactors are positioned along each of the rails of the bus, a device for measuring a total electrical impedance level between the chassis and each of the rails, and a controller for determining a welded contactor condition of at least one of the contactors based on the measured total electrical impedance level.
